' To all whom it may concern:

Be it known that I, JACOB G. W. MARTENS, of the city, county, and Stateof New York, have invented a new and useful Composition of Matter to beused as a Paint, of'which the following is a specification. v

The composition consists of the following ingredients combined in aboutthe proportions stated: Bone-black, two pounds; softwogdmharqga hpnepound; hard-wood charcoal one pound; lgdlgggd, one pound; bojle dlinseedloil, one gallon; water, one quart; salt-' filter, two ounces.

" In order to prepare the composition I proceed as follows: Thesaltpeter is dissolved in one quart of water, and then the four poundsof finely-pulverized bone-black and charcoal are added and the mass isleft to stand for a few days to thoroughly dissolve, after which the redlead is added. The whole substance is thoroughly mixed and then thelinseed-oil added, slowly stirring the mass all the time.

The paint is then ready and can be used for all purposes for which paintis now used; but! it is principally intended for coating the bottoms ofships to prevent barnacles from fasten-E ing on the same. .It prev n andoth i; gpgta ls yghen coated Tfoi'n' andwhen t appliedtbtieesfivddtlfaiid" Eher substances If it preserves them from theelements and from insects.
